# DOMImplementationLS

`public interface DOMImplementationLS`
``

org.w3c.dom.ls.DOMImplementationLS

`DOMImplementationLS` contains the factory methods for creating Load and Save objects.

The expectation is that an instance of the `DOMImplementationLS` interface can be obtained by using binding-specific casting methods on an instance of the `DOMImplementation` interface or, if the `Document` supports the feature `"Core"` version `"3.0"` defined in [DOM Level 3 Core] , by using the method `DOMImplementation.getFeature` with parameter values `"LS"` (or `"LS-Async"`) and `"3.0"` (respectively).

See also the Document Object Model (DOM) Level 3 Load and Save Specification.

## Summary

### Constants
`short` | `MODE_ASYNCHRONOUS` Create an asynchronous `LSParser`.
`short` | `MODE_SYNCHRONOUS` Create a synchronous `LSParser`.

### Public methods
`abstract LSInput` | `createLSInput()` Create a new empty input source object where `LSInput.characterStream`, `LSInput.byteStream` , `LSInput.stringData` `LSInput.systemId`, `LSInput.publicId`, `LSInput.baseURI`, and `LSInput.encoding` are null, and `LSInput.certifiedText` is false.
`abstract LSOutput` | `createLSOutput()` Create a new empty output destination object where `LSOutput.characterStream`, `LSOutput.byteStream`, `LSOutput.systemId`, `LSOutput.encoding` are null.
`abstract LSParser` | `createLSParser(short mode, String schemaType)` Create a new `LSParser`.
`abstract LSSerializer` | `createLSSerializer()` Create a new `LSSerializer` object.

## Constants

### MODE_ASYNCHRONOUS

    public static final short MODE_ASYNCHRONOUS

Create an asynchronous `LSParser`.

Constant Value: 2 (0x00000002)

### MODE_SYNCHRONOUS

    public static final short MODE_SYNCHRONOUS

Create a synchronous `LSParser`.

Constant Value: 1 (0x00000001)

## Public methods

### createLSInput

    public abstract LSInput createLSInput ()

Create a new empty input source object where `LSInput.characterStream`, `LSInput.byteStream` , `LSInput.stringData` `LSInput.systemId`, `LSInput.publicId`, `LSInput.baseURI`, and `LSInput.encoding` are null, and `LSInput.certifiedText` is false.

Returns
`LSInput` | The newly created input object.

### createLSOutput

    public abstract LSOutput createLSOutput ()

Create a new empty output destination object where `LSOutput.characterStream`, `LSOutput.byteStream`, `LSOutput.systemId`, `LSOutput.encoding` are null.

Returns
`LSOutput` | The newly created output object.

### createLSParser

    public abstract LSParser createLSParser (short mode,
                    String schemaType)

Create a new `LSParser`. The newly constructed parser may then be configured by means of its `DOMConfiguration` object, and used to parse documents by means of its `parse` method.

Parameters
`mode` | `short`: The `mode` argument is either `MODE_SYNCHRONOUS` or `MODE_ASYNCHRONOUS`, if `mode` is `MODE_SYNCHRONOUS` then the `LSParser` that is created will operate in synchronous mode, if it's `MODE_ASYNCHRONOUS` then the `LSParser` that is created will operate in asynchronous mode.
`schemaType` | `String`: An absolute URI representing the type of the schema language used during the load of a `Document` using the newly created `LSParser`. Note that no lexical checking is done on the absolute URI. In order to create a `LSParser` for any kind of schema types (i.e. the LSParser will be free to use any schema found), use the value `null`. Note: For W3C XML Schema [XML Schema Part 1] , applications must use the value `"http://www.w3.org/2001/XMLSchema"`. For XML DTD [XML 1.0], applications must use the value `"http://www.w3.org/TR/REC-xml"`. Other Schema languages are outside the scope of the W3C and therefore should recommend an absolute URI in order to use this method.

Returns
`LSParser` | The newly created `LSParser` object. This `LSParser` is either synchronous or asynchronous depending on the value of the `mode` argument. Note: By default, the newly created `LSParser` does not contain a `DOMErrorHandler`, i.e. the value of the " error-handler" configuration parameter is `null`. However, implementations may provide a default error handler at creation time. In that case, the initial value of the `"error-handler"` configuration parameter on the new `LSParser` object contains a reference to the default error handler.

Throws
`DOMException` | NOT_SUPPORTED_ERR: Raised if the requested mode or schema type is not supported.

### createLSSerializer

    public abstract LSSerializer createLSSerializer ()

Create a new `LSSerializer` object.

Returns
`LSSerializer` | The newly created `LSSerializer` object. Note: By default, the newly created `LSSerializer` has no `DOMErrorHandler`, i.e. the value of the `"error-handler"` configuration parameter is `null`. However, implementations may provide a default error handler at creation time. In that case, the initial value of the `"error-handler"` configuration parameter on the new `LSSerializer` object contains a reference to the default error handler.
